The Tubular Centrifuge Working Principle: How Is It Working?

March 28, 2024

The tubular bowl centrifuge is a centrifugal separation equipment with a high separation factor. This type of machine is commonly used in industrial settings for solid-liquid and liquid-liquid-solid separations. The tubular bowl centrifuge is easy to use, produces a lot of juice, takes up little room, and separates materials effectively. Its specialty is low concentration, high viscosity, fine solid particles, and small solid-liquid specific gravity difference solid-liquid separation.

Origin For The Concept Of Energy

The energy wasn't used to measure work until late in mechanics' development. Classical mechanics can be developed without energy. Galileo first proposed energy in the 17th century. He realized that when a weight is lifted with a pulley system, the force multiplied by the distance (the work) remains constant even if either factor changes. In the 17th century, vis viva—living force—was introduced as a quantity proportional to the product of mass and the square of velocity. Energy was used to describe vis viva in the 19th century.


Isaac Newton's first law of motion links force to mass acceleration. The integrated force acting on the mass will certainly be of interest. Two types of integral of the force acting on the mass can be defined. The spatial integral of the force is its action along the line of action, while the temporal integral is its action on the mass over time.


Evaluation of the spatial integral yields a quantity representing the force-induced change in mass kinetic energy and is half the vis viva. However, temporal integration evaluates the force-induced mass momentum change. The German philosopher-scientist Gottfried Wilhelm Leibniz favored the spatial integral as the only true measure of force, while René Descartes preferred the temporal integral. In the 18th century, French physicist Jean d'Alembert proved that both methods of measuring the effect of a force on a mass were valid and that the controversy was over nomenclature.


Many scientists independently recognized energy conservation in the first half of the 19th century. The preservation of kinetic, potential, and elastic energy in a closed system under no friction is useful. On closer inspection, friction, which limits classical mechanics, generates heat at the contact surfaces of a block sliding on a plane, in the bulk of a fluid where a paddle is turning, or in any other expression of “friction.” Hermann von Helmholtz of Germany and James Prescott Joule of England identified heat as energy in the 1840s.


At this time, Joule experimentally proved the mechanical-heat energy relationship. As more detailed descriptions of natural processes were needed, rational theories or models were used to quantify the energy change in the process and include it and its energy balance in the system of interest, subject to energy conservation. This method has worked for converting nuclear mass into energy in nuclear fusion and fission and for burning fuel and oxidizer molecules in an engine to produce heat energy converted to mechanical energy to run a machine.

Types And Their Workings

GF Tubular Bowl

The GF tubular centrifuge is a high-speed solid-bowl type machine that can continuously separate two immiscible liquids with different densities. Separating a tiny amount of contaminants from liquids is another common use for this centrifuge.


A powerful centrifugal force field is created as the bowl spins rapidly around its axis, thanks to the transmission belt and tension wheel that transfer power from the motor to the driven wheel. The material goes into a liquid inlet at the base of the drum. As the tubular bowl centrifuge spins, the dense liquid flows to the top of the bowl and out the top, while the less dense liquid forms an inner ring and goes to the liquid outlets there. Minor particles Once the machine is turned off, it is manually emptied from the bowl after it has settled on the wall.

GQ Tubular Bowl

A high-speed solid bowl-type machine is ideal for continuously removing solids from liquids with density differences, and the GQ continuous tubular centrifuge is just that. The parts that make it up are the body, the gearbox, the bowl, and the bearing seat that allows liquid to enter the liquid collection plate. A flexible main shaft occupies the upper half of the bowl, while a damping floating bearing occupies the lower half.


The material is introduced at the bottom through the liquid inlet as the bowl spins rapidly around its axis, creating a powerful centrifugal force field, thanks to the transmission belt that transfers power from the tension pulley to the passive pulley. Centrifugal force causes the particles in the liquid phase to move through the solid phase. The sediment layer forms as the solid phase, which is denser than the liquid phase, settles to the inside of the bowl over time, and the clarified liquid is released through the top valve. After the process is shut down, manually remove the sediment from the bowl wall if its thickness impacts the clarity of the liquid phase or reaches the rated slag capacity of the bowl.

Benefits of Tubular Centrifuge

There are a lot of situations where the continuous tubular centrifuge is better than other separation methods because of all the benefits it provides. Here are a few of the main advantages:

High Efficiency

Even in complicated mixtures, the components can be quickly and efficiently separated using their large sedimentation area and high rotational speed.


Saving Energy

Because of their low initial investment and high potential for future use, numerous sectors highly prized them. You can save money on consumables by washing and reusing the tubular bowl centrifuge tubes.

Compact Design

The machine's small footprint makes it easy to incorporate into preexisting process lines and conserves precious floor space in manufacturing facilities.

Ease of Maintenance

The machines are easy to operate and maintain because of their simple design with few moving parts. They cut down on operational expenses and downtime thanks to their long service life and low maintenance requirements.

Ongoing Function

It runs continuously, unlike batch centrifuges, which means more throughput and better product quality every time.

Low Cost

Many industries find them worthwhile investments due to their cost-effectiveness and repeatability. The consumables cost can be reduced because the tubular bowl centrifuge tubes can be easily cleaned and reused.

Applications Of Tubular Centrifuge

Because of their small size, efficiency, and adaptability, tubular centrifuges find use in many different fields and applications. Here are a few important uses:

Pharmaceutical Sector

Vaccines, antibiotics, and other biopharmaceutical goods rely on it heavily. They aid in the purification process by removing cells, cell debris, and other contaminants from the product stream.

Food and Beverage Industry

The food and beverage industry commonly uses clarifying juices, wines, and other products. They aid in the process of clarifying the product by removing solids like fruit pulp and yeast.

Manufacturing of Chemicals

The chemical industry uses continuous tubular centrifuges to separate various types of liquid-liquid and liquid-solid mixtures, including water and oil.

Environmental Applications

Centrifuges have many uses in the environmental field, including sludge dewatering and wastewater treatment. For more effective garbage disposal and water recycling, they aid in separating solid pollutants from water.
